Özet
Hayward ve Matua (Actinidia deliciosa A. Chev.) kivi çeşitlerine ait odun çeliklerin köklendirilmesinde, en uygun çelik alma zamanı, çelik tipi ve IBA dozlarının saptanmasını amaçlayan bu çalışma, 2002-2003 yılları arasında Rize’de yürütülmüştür. Çalışmada, çelikler 1 Ocak ve 1 Şubat olmak üzere 2 farklı zamanda alınmıştır. İki ve üç gözlü olarak hazırlanan çeliklere 0, 2000, 4000 ve 6000 ppm IBA uygulaması yapıldıktan sonra, alttan ısıtma ve mistleme ünitesine sahip, ısıtmasız cam serada perlit ortamında köklenmeye alınmıştır. Köklendirme ortamından 120 gün sonra sökülen çeliklerde köklenme ve canlılık oranları, en gelişmiş kök uzunluğu ve çapı, kök sayısı ve kalitesi belirlenmiştir. Araştırma sonucunda, köklenme ve kök kalitesi bakımından en yüksek sonuçlar Hayward için 1 Ocak, Matua için ise 1 Ocak ve 1 Şubat tarihlerinde 3 gözlü olarak hazırlanarak, 4000 ile 6000 ppm IBA uygulaması yapılan çeliklerden alınmıştır. Hayward çeşidinde % 52.0-73.0, Matua çeşidinde % 48.0-83.0 arasında değişen köklenme oranları elde edilmiştir
This study was carried out to determine the suitable time for preparation of cuttings, type of cuttings and IBA concentrations to root the hardwood cuttings of Hayward and Matua kiwifruit (Actinidia deliciosa A. Chev.) cultivars in Rize during 2002 and 2003. The hardwood cuttings were used on 1 January and 1 February. After pre-treating with 0, 2000, 4000 and 6000 ppm IBA, the cuttings with two or three shoot buds were rooted in unheated greenhouse with a bottom heated mist propagation frame containing perlite medium. Hardwood cuttings were exposed to the rooting media for 120 days and then they all were removed from the media to determine the rooting and viability rates, the most developed roots in both length and width, lateral root number and root quality. As a result of the study, the highest rooting and rooting quality were obtained from hardwood cuttings of cv. Hayward prepared with three shoot buds on 1 January and cv. Matua prepared with three shoots buds on 1 January and 1 February. All the cuttings were treated with 4000 and 6000 ppm IBA. Rooting ration was found to be 52.0 % - 73.0 % and 48.0 % - 83.0 % for cv. for Hayward and Matua, respectively.
